Hauv electromagnetism thiab electronics, inductance yog qhov nyiam ntawm hluav taws xob tus thawj coj tiv thaiv kev hloov pauv hauv cov hluav taws xob tam sim no ntws los ntawm nws. Nws yog aproportionality yam uas nyob ntawm cov geometry ntawm circuitconductors thiab cov magnetic permeability ntawm cov khoom nyob ze.

Cov lus nug tseem ceeb yog, vim li cas cov xov hlau muaj inductance?

Inductance hauv paus Inductance yog tshwm sim los ntawm cov magnetic fieldgenerated los ntawm hluav taws xob tam sim no ntws nyob rau hauv ib tug hluav taws xob Circuit Court. Feem ntau coils ntawm hlau yog siv raws li ib tug coilincreases lub coupling ntawm lub magnetic teb thiab ua rau kom cov nyhuv.

Tsis tas li ntawd, cable capacitance yog dab tsi? Capacitance piav qhia txog lub peev xwm ntawm ob tus neeg siv khoom, sib cais los ntawm cov khoom siv insulating, khaws cov nqi. Capacitance yog ib qho teeb meem tshwj xeeb nrog cov ntaub ntawv lossis teeb liab kab . Thaum lub teeb liab hluav taws xob kis tau los ntawm cov khub atwisted lossis coaxial hom kab , tus nqi tsim upacross lub rwb thaiv tsev ntawm cov conductors.

Xav txog qhov no, dab tsi yog inductance siv rau?

Inductors yog dav siv hauv alternating tam sim no (AC) cov khoom siv hluav taws xob, tshwj xeeb hauv cov khoom siv xov tooj cua. Lawv yog siv rau thaiv AC thaum tso cai rau DC hla; inductors tsim los rau lub hom phiaj no yog hu ua chokes.

Dab tsi yog tus kheej inductance thiab kev sib nrig sib inductance?

Tus kheej inductance yog txhais raws li tus induction ntawm ib tug voltage nyob rau hauv ib tug tam sim no-nqa hlau thaum lub tam sim no nyob rau hauv cov hlau nws tus kheej hloov. Nyob rau hauv cov ntaub ntawv ntawm tus kheej - inductance , magnetic teb tsim los ntawm kev hloov tam sim no hauv Circuit Court nws tus kheej induces ib tug voltage nyob rau hauv tib lub circuits.
